PRESSER -FOOT AND GUIDE FOR SCROLL-SAWS.

SPECIFICATION forming part of Letters Patent No. 233,059, dated October5, 1880.

Application filed July 10, 1880.

To all whom it may concern:

Be it known that I, FRANK M. Woons, of York, in the county of Clark andState of Illinois, have invented certain new and useful Improvements inPresser-Feet and Guides for Scroll-Saws; and 1 do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable oth ers skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in scroll-sawing machines; and itconsists in the adjustable slotted parts which form the arm forsupporting the guide and presser-foot, as will be more fully describedhereinafter.

The object of my invention is to provide a scroll-sawing machine inwhich only a single end of the saw is attached to any device, and havingthe guide at the same time act as a presser-foot, and to regulate thepressure of this foot upon the material being sawed by the arm whichsupports it.

Figure l is a side elevation of my invention. Fig. 2 is an end view ofthe same. Fig. 3 is a detail view.

A represents the frame of the machine, upon the top of which the table Bis secured; livoted in the lower part of this frame is the treadle O,which has one end connected to the driving-wheell) by means of theconnect ing-rod E. From this driving-wheel passes the belt F, whichoperates the wheel G on the shaftII, which shaft has a balance-wheel, I,secured to its other end. This Wheel G is provided with a wrist-pin, towhich is fastened a connecting-rod, J, which has its lower end.tastel'ied to the vertically-moving rod L. To the upper end of this rodL the lower end of the saw is rigidly clamped by means of any suitabledevice. This saw extends up through the table, but instead of having itsupper end attached to an arm, spring, ora guide of some kind, the end isleft entirely free, so that it plays loosely [up and down in the groove0,

which is made in the combined guide and presser-foot N.

By not connecting the upper end of this saw to any other device I findthat the saw operates just as well, is not so liable to be broken, andis much more .easily attached to the machine, at the same time that thefriction is correspondingly reduced. This guide having a slot in itsedge for the saw to work in, serves also as a presser-foot to hold downthe material upon which the saw is operating, and has a vertical slot,P, made through it, so that it can be adjusted up and down to suit thedifferent thicknesses of material being sawed. Thiscombinedpresser-footand gnideis I clamped to the front end of the arm whichsupports it, and this arm is composed of the two slotted horizontalpieces R and the curved piece S. By means of the slots in the two piecesR the length of the arm can be increased or decreased at will, and thusaugment or diminish the pressure of the foot upon the material.

By making the curved part S elastic the pressure of the presser-foot canbe regulated at will. By extending the arm by means of the slots atgreater sweep is given to the arm and a finer adjustability to thepresser-foot.

Having thus described my invention, I claim-- In a scroll-sawingmachine, the combination of the two supporting-arms R, an intermediateelastic connecting-arm, S, and a presserfoot, N, fastened to the freeend of the upper one of the arms R, the arm S being made adjustable backand forth on the arms, so as to increase or decrease the pressure of thefoot by lengthening or shortening the leverage, substantially as setforth.

In testimony that I claim the foregoing I have hereunto set my hand this23d day of June, 1880.
